Why does Chienaux’s study suggest the reliability of the classification and diagnosis of SZ
-Using the DSM, one psychiatrist diagnosed 26 people and the other diagnosed 13 people
How many participants were the psychiatrist asked to diagnose either using the DSM or ICD
100 participants
Using the ICD, how many of the participants did each psychiatrist diagnose
-44 and the other diagnosed 24
What does Chienaux’s study show?
-Shows poor inter-rater reliability as one of the psychiatrist diagnosed almost double the amount than the other psychiatrist.
Outline system overlap
-where two or more conditions share similar symptoms
example of a condition that shares similar symptoms to SZ
-both SZ and depression involve negative symptoms such as avolition
What does system overlap effect in regards to reliability and validity of classification and diagnosis of SZ
-effects the accuracy and consistency
